Cause of the Laramide orogeny

[edit]

The cause of the Laramide orogeny being shallow subduction of the Farallon plate is disputed. Increasingly, collision of a large archipelago or "ribbon continent," with subsequent northward translation, is being advanced by N. American cordillera geologists as the cause of the Laramide and Sevier orogenies.

At the very least, the shallow subduction theory should not be presented as absolute fact. 97.115.146.255 (talk) 23:52, 17 September 2023 (UTC)[reply]
